'Jesus sent His Holy Spirit. The Apostles celebrated Mass in the Cenacle the evening of Pentecost itself. That great day was crowned by the Communion of all the Faithful of the Church, the disciples, and the newly baptized. "When enemies are reconciled, they invite one another to festivals of peace. Ah, well! on this day Jesus Christ shows us that He has reconciled us to His Father by sending us the Spirit of Peace. This day ought to end in the inebriating joys of the Eucharistic Banquet."'

St. Peter Julian Eymard
